Subject: [PATCH] batman-adv: use eth_hw_addr_random() instead of
random_ether_addr()
Use eth_hw_addr_random() instead of calling random_ether_addr()
to set addr_assign_type correctly to NET_ADDR_RANDOM.
Remove dev_addr in interface_setup(), it's not needed anymore.
Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.
v2: use bitops, adapt to eth_hw_addr_random()
